Definitions

  • This invention relates to a switchgear cabinet with a rack and/or panel elements, wherein a mounting plate can be attached to an interior of the switchgear cabinet, the lower edge of the mounting plate has sliding elements, one or several spacing elements are fastened on a rear panel element and/or on rear parts of the rack, by which the mounting plate is supported in the mounting position, and the mounting plate has fastening receivers in the area of the lower edge and the upper edge which, in the installation position of the mounting plate, cooperate with fastening elements of the lower and upper contact elements and fix the mounting plate rigidly in place.
  • Switchgear cabinets can be embodied with or without a rack, wherein a switchgear cabinet interior, in which the mounting plate with the attachments are installed, is always enclosed by the panel elements. A distance from the parallel rear wall, which is predetermined by the spacing elements, is always maintained for safety reasons. In this case, the mounting plates can have a considerable weight and are thus hard to manipulate as far as the installation and access in case of supplementary and/or repair work is concerned.
  • bearing elements are applied in the area of the lower edge of the rear wall, into which the mounting plate could be inserted and pivotably seated.
  • the mounting plate is also maintained in the area of the upper edge of the mounting plate on spacing elements by releasable connections.
  • the installation of heavy mounting plates is not simplified by this embodiment. In case of supplementary or repair work, after releasing the upper connections the mounting plate can be put into an inclined position in which a rear portion of it is accessible.
  • this object is achieved by introducing the mounting plate into the switchgear cabinet interior.
  • the sliding elements are supported with a sliding face on an interior surface of a bottom plate and cover plate of the switchgear cabinet facing the switchgear cabinet interior and are guided on it, wherein the bottom plate or the cover plate faces the attachment area.
  • the arrangement of fastening receivers at the lower edge and the upper edge, as well as the use of spacing elements with fastening elements in the facing lower or upper area of the rear wall, allows the two placement variations of the switchgear cabinet.
  • This fastening results in an unequivocal installation position with a fixation which cannot be displaced in the direction toward the lateral walls.
  • the sliding elements on the lower edge of the mounting plate and their guidance on the bottom plate or the cover plate render guide rails superfluous. Fixation of the lower edge at the facing spacing elements is taken over by the receiving grooves of the spacing elements, which assure fixation without possible displacement of the mounting plate, perpendicularly with respect to the rear wall.
  • the mounting plate in the installed position the mounting plate can be permanently fixed in place, which can be designed in a known manner, or which can also be accomplished according to this invention by an appropriate layout of the fastening elements.
  • the sliding elements do not hamper the lateral fastening of the mounting plate by the fastening receivers and the fastening elements
  • the sliding elements are placed onto the mounting plate outside of the fastening receivers of the lower edge, and the sliding elements can be removed from the lower edge of the mounting plate after attaining the installed position.
  • the fastening receivers prefferably be on the lower edge and the upper edge and embodied as vertical recesses of the mounting plate, which are matched in the horizontal direction to the dimensions of bolts designed as fastening elements of the spacing elements.
  • the fastening elements of the spacing elements can be embodied as threaded bolts, onto which screw elements can be screwed for fixing the mounting plate, which is in the installed position, in place.
  • the insertion of the lower edge of the mounting plate into the receiving grooves of the spacing elements is achieved if the sliding elements guide the lower edge of the mounting plate at a distance from the bottom plate or the cover plate so that, following the placement of the mounting plate against the lower or upper spacing elements, the lower edge is located above the receiving grooves of the facing spacing elements.
  • the mounting plate can be lowered and introduced with the lower edge into the receiving grooves of the facing spacing elements.
  • the removal of the sliding elements can be made easier if during the removal the sliding elements are shifted into laterally arranged enlarged recesses of the lower edge, which permit the insertion of the lower edge into the sliding element.
  • the installation of the mounting plate can be made easier if the upper spacing elements are provided with a ramping support in the area of the cover plate which, when introducing the upper edge of the mounting plate into the lower spacing elements in the area of the bottom plate, lift the mounting plate into the installation position.
  • the vertical installation position of the mounting plate is fixed and the removal of the sliding elements is made possible.
  • the mounting plate with the sliding elements is supported on the bottom plate by a cable introduction opening, in connection with a bottom plate with a cable introduction opening and an upwardly beveled L-shaped edge, the sliding elements on the lower edge of the mounting plate slide on the edge and additionally enter the cable introduction opening with a shoulder and are laterally guided on the edge.
  • FIG. 1 is a perspective front view of a switchgear cabinet, into which a mounting plate is installed, wherein a bottom plate has a cable introduction opening and faces the attachment area;
  • FIG. 2 is a partial perspective view of the mounting plate with a fastening receiver of a lower edge and sliding element, which can be placed on it;
  • FIG. 3 is a partial view corresponding to FIG. 2 with a different sliding element and a different attachment to the lower edge of the mounting plate;
  • FIG. 4 shows the switchgear cabinet in accordance with FIG. 1 in a front perspective view, wherein the cover plate is facing the attachment area and the mounting plate is shown during introduction into the switchgear cabinet interior.
  • FIG. 5 shows a prior art switchgear cabinet comprised of rack elements.
  • the switchgear cabinet 10 represented in FIG. 1 is constructed without a rack.
  • the bottom plate 11 , the cover plate 15 , the rear wall 16 and the lateral walls 17 and 18 enclose the switchgear cabinet interior, in which the mounting plate 20 can be installed spaced apart from the rear wall 16 .
  • the bottom plate 11 has a cable introduction opening 12 , off of which an L-shaped edge with edge sections 13 and 14 is beveled. The L-shaped edge faces the interior of the switchgear cabinet 10 .
  • a cabinet door, not represented, is attached in the area of or near the open front side.
  • Spacing elements 40 are attached in the lower and upper area of the rear wall 16 , which form a stop when the mounting plate 20 is installed and thus determine a distance to the rear wall 16 .
  • the mounting plate 20 has fastening receivers 22 and 26 , which are designed as recesses.
  • the spacing elements 40 have fastening elements 41 in the shape of protrusions, such as bolts at the top or shoulders at the bottom, which can be embodied as threaded bolts.
  • the fastening receivers 22 and 26 have a horizontal width corresponding to a diameter of the fastening elements 41 .
  • sliding elements 30 are placed on the lower edge 21 of the mounting plate 20 , wherein the lower edge 21 are introduced into the transverse slits 31 of the sliding elements 30 .
  • the sliding elements 30 have sliding faces 32 facing the edge section 14 of the bottom plate 12 , on which the bottom plate 20 is supported and pushed into the switchgear cabinet interior in the direction toward the rear wall 16 , as indicated by the reference numeral “ 1 ” in FIG. 1 .
  • the fastening element 41 of the two lower spacing elements 40 is introduced into the fastening receivers 22 , of the mounting plate 20 , as indicated by the reference numeral “ 2 ” in FIG. 1 .
  • two sliding elements 30 and two spacing elements 40 with fastening elements 41 are preferably provided.
  • more than two fastening locations can be provided, as indicated by the fastening receivers 26 at the upper edge 25 of the mounting plate 20 .
  • the mounting plate 20 can have additional fastening receivers 23 and 27 .
  • the vertical sides of the mounting plate 20 can be reinforced by bevels 28 .
  • the mounting plate 20 When raising the mounting plate 20 , the lower edge 21 engages the receiving grooves 42 of the lower spacing elements 40 .
  • the mounting plate 20 supported here by the occurring lever forces, is lifted opposite the direction of gravity, and the sliding elements 30 are lifted off the bottom plate 12 .
  • the sliding elements 30 can then be removed from the lower edge 21 . If the fastening elements 41 of the spacing elements 40 are embodied as threaded bolts, the installation position can be fixed by screw elements screwed onto them.
  • FIG. 3 shows, if a closed bottom plate 11 forms the support for the sliding face 32 , the lower edge 21 of the mounting plate 20 can also support only one centered, wide sliding element 30 .
  • the spacing elements 40 can also have ramping supports 43 which, during introducing the upper edge 26 into the receiving grooves 42 of the spacing elements 40 in the area of the bottom plate 11 , determine the final installed position, as shown in FIG. 4 , in which the cover plate 15 of the switchgear cabinet 10 faces the attachment area.
  • the installation process occurs in three steps, of which the first step is indicated by the reference numeral “ 1 ” in FIG. 4 .
  • Fixation in the lateral direction is again taken up by the fastening receivers 26 and 22 , as well as the fastening elements 41 of the spacing elements 40 .
